A motor boat takes 6hours to cover 100km downstream and 30 km upstream if the boat goes 75 km upstream and 75 km downstream find the speed of the boat in still water and find the speed of the stream |
|
Answer» Step-by-step explanation: ⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇ ▶⏩ Let the speed of the boat in still water be X km/hr. and, the speed of the boat in stream be y km/hr. Then, ↪➡ Speed UPSTREAM= ( x - y ) km/hr. ↪➡ and, speed downstream = ( x + y ) km/hr. ▶⏩ TIME taken to cover 30km upstream ▶⏩ Time taken to cover 24km downstream ▶⏩ Total time taken = 6hrs. ▶⏩ Again, time taken to cover 75km upstream ( RETURNING 75km back from 75km downstream). ▶⏩ Time taken to cover 75km downstream ▶⏩ Total time taken 8hrs. in equation (1) and (2), we get:-) ↪➡ 30u + 100v = 6. ↪➡ 15u + 50v = 3.....................(3) and, ↪➡ 75u + 75v = 8.....................(4) ▶⏩ Multiply by 5 in equation (3). we get, ↪➡ 75u + 250v = 15....................(5) ▶▶ Substract in equation (4) and (5). 75u + 250v = 15 75u + 75v = 8 (-)......(-)...........(-) ______________ => 175v = 7. ▶⏩ Put the value of ‘v’ in equation (3). and, ▶⏩ Substract equation (6) and (7). x - y = 15 x + y = 25 (-)...(-)....(-) _________ => -2y = -10 ▶⏩ Now, put the value of ‘y’ in equation (6). ↪➡ x - 5 = 15. ↪➡ x = 15 + 5. ✅✅Hence, the speed of motorboat in still water is 20 km/hr. and , the speed of motorboat in stream is 5 km/hr.✔✔ please mark as brainlist answer and follow me please thank answer |

THE COST OF AN ELECTRICAL GADGET AND THE COST OF PLUMBING MATERIAL WERE IN THE RATIO 8:6 LAST YEAR, THIS YEAR EACH COST HAS REDUCED BY Ghc 4.00 and their ratio changed to 7:5, respectively taking the initial cost of the electrical gadget to be Ghep and that of the plumbing material to be Ghe q, calculate the value of p and q |
|
Answer» Given : cost of an ELECTRICAL gadget and the cost of a plumbing material were in the ratio 8:6 last year. This year, each cost was reduced by 4.00 and has changed to 7:5 respectively To find : initial cost of the electrical gadget & plumbing material Solution: cost of an electrical gadget = 8x = p cost of a plumbing material = 6x = q each cost was reduced by 4.00 cost of an electrical gadget = 8x - 4 cost of a plumbing material = 6x - 4 New ratio 7 : 5 => (8x - 4)/ (6x - 4) = 7/5 => 5(8x - 4) = 7(6x - 4) => 40x - 20 = 42x - 28 => 2x = 8 => x = 4 p = 8x = 8 * 4 = 32 q = 6x = 6 * 4 = 28 initial cost of the electrical gadget p = 32 initial cost of the plumbing material q = 28 Learn More: The ratio of the number of students in THREE classes A,B and C is 3:7 ...

The largest no which divides 70 and 125 leaving the reminder 5 and 7 |
|
Answer» Answer: please follow me Step-by-step explanation: SINCE, 5 and 8 are the REMAINDERS of 70 and 125, RESPECTIVELY. Thus, after subtracting these remainders from the numbers, we have the numbers 65 = (70 – 5), 117 = (125−8), which is DIVISIBLE by the required number. Hence, 13 is the largest number which divides 70 and 125, leaving remainders 5 and 8 |
