The distance travelled dd is the rate rr multiplied by time tt:

\(\displaystyle{d}={r}{t}\)

Substitute r=50 miles per hour and t=2.5 hours (2 hr 30 min):

\(\displaystyle{d}={\left({50}\right)}{\left({2.5}\right)}\)

\(\displaystyle{d}={125}{m}{i}\le{s}\)

\(\displaystyle{d}={r}{t}\)

Substitute r=50 miles per hour and t=2.5 hours (2 hr 30 min):

\(\displaystyle{d}={\left({50}\right)}{\left({2.5}\right)}\)

\(\displaystyle{d}={125}{m}{i}\le{s}\)
