Question

Two cars A and B are moving in same direction with speed 10 m/s and 8 m/s respectively. If both cars start from same point, then distance between cars Aand B after 1 minute will be
(a) 120m
(b)100m
(c)80m
(d)410m​

Answer 1

Answer:

(a) 120m

Explanation:

10x60=600m, 8x60=480m

600-480=120m

Answer 2

Answer:

Two cars A and B are moving in same direction with speed 10 m/s and 8 m/s respectively. If both cars start from same point, then distance between cars A and B after 1 minute will be 120meter.

Explanation:

Speed = $\frac{Distance}{Time taken}$

So Speed is rate change of its position with respect of time

In question we have that two car start from same point with different speed so one car speed will fast compare with another car so there will be some distance between two car.

Speed of car A = 10m/s

Speed of car B = 8m/s

Distance traveled by car A after 1 minute will be

distance = speed*time taken(second)

1 minute = 60 second

distance = 10*60 $\frac{m}{s}*s$

distance = 600 meter (for car A)

Distance traveled by car B after 1 minute will be

distance = speed*time taken(second)

distance = 8*60$\frac{m}{s} *s$

distance = 480 meter(for car B)

Distance between car A and car B,

Distance traveled by car A - Distance traveled by car B

= 600 meter - 480 meter

Distance between car A and car B = 120 meter
