# Answer on Mechanics | Relativity Question for Nick

Question #13865

A car travels at 67 km/hr for 2.00 hr and 115 km/hr for 3.00 hr. What is its average speed?

Expert's answer

We have that

v1 = 67 km/hr

t1 = 2.00 hr

v2 = 115 km/hr

t2 = 3.00 hr.

Then the average speed is

v = (v1*t1 +

v2*t2)/(t1+t2)

= (67*2 + 115*3)/(2+3)

= 95.8 km/hr

v1 = 67 km/hr

t1 = 2.00 hr

v2 = 115 km/hr

t2 = 3.00 hr.

Then the average speed is

v = (v1*t1 +

v2*t2)/(t1+t2)

= (67*2 + 115*3)/(2+3)

= 95.8 km/hr
