Question

A formula one race car accelerates with a speed of 105km/h in the first 15 minutes and then moves at 212km/h in the next 20 minutes , find the distance travelled by the car.

Answer 1

since
v = d /t
d = v*t
Now for first 15 min
t = 15/60 hr
v=105 km/hr
so D1= 105 * 15/60
D1 =26.25km
Now for next 20 min
t = 20/60 hr
v=212 km/hr
so D2= 212 * 20/60
D2=70.66km
Now Total Distance =
D1+D2
$26.25 + 70.66$
96.1

Answer 2

96.1 is the ans i think so
