Question

Two cars A and B are moving with velocities 20 m/s and 15 m/s in the direction east and west respectively. If

they started from the same place at the same time, what would be the distance between them after 2 min? Find

the distance covered by each car at the same time. (2 min).​

Answer 1

Distance between them is 4,200 meters.

Step-by-step explanation:

Consinder car A:

`{ \bf{distance = speed * time }}`

substitute:

`distance = 20 * (2 * 60) \\ = 2400 \: m`

Consider car B:

`distance = 15 * (2 * 60) \\ = 1800 \: m`

since these cars move in opposite directions, distance between them is their summation:

`distance \: between = { \sum(distance \: of \: each \: car)} \\ = 2400 + 1800 \\ = 4200 \: m`
