Question 8 01 A bus covers a distance of 375 km at a certainspeed in 5 hours. How much time a bike wouldtake at an average speed which is 18 kmph morethan the speed of the bus to cover a distancewhich is 14 km more than the distance travelled bybus?A) 6.23 hoursB) 5.50 hoursC) 4.18 hoursD) 5.23 hours​

Answer»

Step-by-step explanation:

Let the speed of the bus be x km/hr therefore speed of BIKE = (18+x) km/hr

Distance covered by bus = 375 km

Distance covered by bike = (14 + 375)km = 389km

Time taken by bus = 5 hours

Time taken by bike = ?

speed of bus = 375/5 = 75 km/hr

therefore speed of bike = 18+75 = 93 km/hr

hence time taken by bike = distance/speed

= 389/93

= 4.18 hours

Answer = C
