Time taken by the car to cover 260 km is 2.6 hrs
Step-by-step explanation:
- Step 1: Find the speed of the car given distance covered = 150 km and time = 1.5 hrs.
Speed = Distance/Time = 150/1.5 = 100 km/hr
- Step 2: Find the time taken by the car to cover 260 km.
Time = Distance/Speed = 260/100 = 2.6 hrs

we need to find the area of a circle with a radius of 21.
we also need a formula for this, which is
⇒
the known value is r, radius, 21.
after substituting the value into the formula, we obtain:
⇒
now we multiply the radius times itself:
⇒
<u>which can be</u> <u>written</u> <u>as</u>

<u>⇒</u>
and finally, multiply the values
