Question

Susie and Sara traveled together by car and shared the driving. Susie drove for 6.25 hours then Sara gave Susie a break, driving for 2.25 hours. Their total distance is modeled by the expression below. 64(6.25) + 75(2.25) What does the 6.25 in 64(6.25) represent? What about the 64? What does the 2.25 in 75(2.25 represent? What about the 75?

Answer 1

we have the following:

We have that both cases, the value that they do not give us in the statement, but in the expression that models the equation corresponds to susie's speed and Sara's speed.

Susie's peed is 64 and Sara speed is 75.

6.25 the time in hours of Susie andd 2.25 the time in horus of Sara.

This is due to:

`\begin{gathered} s=(d)/(t) \\ d=t\cdot s \end{gathered}`

where, s is speed, t is time and d is distance
