Answer 2

Answer:

• Speed=20m/s
• 20m in 1sec and 100m in 5 secs
• Car travels 90m in 4.5 secs

Explanation:

Speed = distance/ time=500/20=25m/s

Speed is 20m/s

Therefore, car travels

• 20m in 1 sec
• 20*5=100m in 5 secs

Distance=speed *time

90=20*t

T=90/20

T=4.5secs

I hope the answer will help you dear
