Answer 2

Answer: Speed is 120 km

Step-by-step explanation:

Given,

Distance = 420 km, Time = 3.5 hr, S = ?​

We have to find the speed using the formula,

Speed=Distance/Time

Dividing distance by time

=420/3.5

=120 km

Thus, we get the result 120 km

The rate of change of position of an object in any direction is called speed. Speed is a scalar quantity as it has only direction and no magnitude.
