Question

3.
Two Cars, A and B, (starting, at the same time, from the same point) are moving
with average speeds of 40 km/h and 50 km/h, respectively, in the same direction.
Find how far will Car B be from Car A after 3 hours.​

Answer 1

Answer:

Average speed =total distance covered/ total time

car A average speed =40km/h

according to our formula

40 km/h=total distance/3

total distance travell the car A=120km

car Baverage speeed =50km/h

50km/h=total distance/3=150km

total distance travell the B=150km

Acording to our question

the distance between the car A and B =150-120

=30km

Answer 2

Answer:

30Km Diff

Explanation:

Formula~

S x T = D

Car A: 40 (km/h)  x 3 (instead of minutes or its long) = 120km

Car B: 50km/h x 3 = 150km

150 - 120 = 30km difference
