Question

How much time is required to cover a distance of 1.5 km at a speed of 30 km per hour?

Answer 1

Step-by-step explanation:

Speed =distance/time

Here,

Speed=90/1.5 kmph

Let time required to cover 40 km at the same speed be ‘tʼ.

Therefore,

90/1.5 kmph = 40/t

t=0.75 hours =45minutes

Answer 2

Step-by-step explanation:

• time = distance ÷ SPEED
• Time = 30÷ 1.5 = 20
• time = 20 minutes.
