Question

Bus A and Bus B leave school on a field trip when a stopwatch reads zero. Bus A travels at a constant 50 km/h, and Bus B travels at a constant 75 km/h. How far are the two buses from school when the stopwatch reads 1.5 h?
a.
Bus A is 76.5 km from school, Bus B is 51.5 km from school
c.
Bus A is 75 km from school, Bus B is 112.5 km from school
b.
Bus A is 112.5 km from school, Bus B is 75 km from school
d.
Bus A is 51.5 km from school, Bus B is 76.5 km from school

Answer 1

you have to understand how to calculate with physical fractions for this problem

\[velocity = \frac{ 50km }{ h }\]
the fraction tells you the bus does 50 km PER hour
thats how the fraction works, ok?

Answer 2

C
