1.	A car moving over a straight path, covers a distance d with constant aspeed of 40km/h and then the same distance with speed 60km/h , the average speed of car is
Answer» Answer: Given : ▪ A car covers first half of total distance with speed 40kmph and second half of total distance with speed 60kmph. To FIND : ▪ Average speed of the car. Concept : ✏ If body covers first half of total distance with speed v1 and second half of total distance with speed V2, then average speed of the body is given by ☞ (v)AV = 2v1v2/v1+v2 ✏ Average speed is defined as the RATIO of total distance travelled to the total time taken. ✏ It is a scalar quantity. Calculation : → (v)av = 2v1v2/v1+v2 → (v)av = 2(40)(60)/(40+60) → (v)av = 4800/100 → (v)av = 48kmph Explanation: *Mark* me *as brainlist*...

Answer»

Answer:

Given :

▪ A car covers first half of total distance with speed 40kmph and second half of total distance with speed 60kmph.

▪ Average speed of the car.

Concept :

✏ If body covers first half of total distance with speed v1 and second half of total distance with speed V2, then average speed of the body is given by

☞ (v)AV = 2v1v2/v1+v2

✏ Average speed is defined as the RATIO of total distance travelled to the total time taken.

✏ It is a scalar quantity.

Calculation :

→ (v)av = 2v1v2/v1+v2

→ (v)av = 2(40)(60)/(40+60)

→ (v)av = 4800/100

→ (v)av = 48kmph
