Answer 1

Estimated Answer=1/2 hour

Exact Answer= 49/101 hour

Explanation:

Steady speed of the object =10 and one tenth km​/h = 10 1/10 km

Distance to be Covered=4 and nine tenths km = 4 9/10 km

To the nearest integer,

Steady speed of the object = 10 km/hr

Distance=5km

= 5/10 =1/2 hr

The estimated answer is 1/2 hr.

The exact time taken is 49/101 hours
