Since with have both the distance and the velocity of both cars, we can calculate their velocities, which is distance/time.

Roger:

2 miles in 7.5 minutes -> 1h = 60min -> \frac{7.5 min}{60 min} = 0,125h

2 miles in 0,125h -> \frac{2 miles}{0,125h} = 16miles/hour = 16mph

Natalie

2 miles in 6.5 minutes -> 1h = 60min -> \frac{6.5min}{60min} = 0,1083h

2 miles in 0,1083h -> \frac{2 miles}{0,1083h} = 18,46 miles/hour = 18,46mph

With their velocities in hand you can draw your own conclusions ;)

Which evidence supports the reasearchers hypothesis?
Vanyuwa [196]

Answer:

The evidence that a researcher decides to use should be from a credible source and should be track-able.

It can or cannot back the hypothesis created by the researcher. In both cases, the researcher must synthesis it properly into his research. It must build a connection and somewhat extends the points discussed in the hypothesis.

Either way it should have a direction. Something that does not connect to the core of research must not be added in it.
