Answer:
Unitary method:
a car travels 60 km in 30 minutes
1 km ---------> 30÷60 = 1/2 minutes
100 KM ------> 1÷2×100 = 50 minutes
Answer:
About 40 Minutes, Or something close to that
Step-by-step explanation:
The car covers 60 km in 90 minutes or its speed = 60 km*60/90 min = 40 km/hr . So to cover 100 km at the same speed it will take 100/40 = 40 Min
