Answer 1

Answer:

A CERTAIN DISTANCE WAS COVERED AT SPEED OF 60 KM/HOUR FOR 3 HOURS

SO , DISTANCE = 60× 3 = 180 KM

SO TIME TAKEN TO COVER THE SAME DISTANCE IN 45 KM/ HOUR = 180 ÷ 45 = 4 HOURS.

Answer 2

Answer:

4 hours

Step-by-step explanation:

Distance = Speed × Time

Distance covered = 60 × 3 = 180 km

Time = Distance/Speed

→ Time taken = 180/45 = 4 hours
