Answer:
The distance travelled at 35 km/hr is 3 km.
Step-by-step explanation:
Let the time be 'x' hrs.
Then the distance travelled at 35 km/hr will be '35x' km.
Also, the distance travelled at 42 km/hr will be '42x' km.
A/q,
42x-35x=21
=> 7x=21
=> x=3
The distance travelled at 35 km/hr is 3 km.
hope it helps!
