First,do 50/12 and that equals 4.16 so basically Terrance will take about 4 hours and 3 minutes and 45 seconds to run.For Jesse,do 50/8 and that equals 6.25. So Jesse will run for 6 hours and 15 minutes and 0 seconds to run

Answer:

The time taken by Terrance and Jesse to cover 50 miles are 4 hours 10 min 6 and hours 15 min respectively.

Step-by-step explanation:

The formula for speed:

\(Speed=\frac{Distance}{Time}\)

It is given that the terrance trains at a rate of 6 miles every half hour, and Jesse trains a t a rate of 2 miles every 15 min.

Speed of Terrance:

\(Speed=\frac{6}{\frac{1}{2}}=12\)

Speed of Terrance is 12 miles every hour.

Speed of Jesse:

\(Speed=\frac{2}{\frac{1}{4}}=8\)

Speed of Jesse is 8 miles every hour.

We need to find the time taken by Terrance and Jesse to cover 50 miles.

\(Time=\frac{Distance}{Speed}\)

Time taken by Terrance is

\(Time=\frac{50}{12}=\frac{48+2}{12}\Rightarrow 4+\frac{2}{12}=4+\frac{1}{6}\)

4 hours +1/6 hours = 4 hours 10 min

Therefore, the time taken by Terrance is 4 hours 10 min.

Time taken by Jesse is

\(Time=\frac{50}{8}=\frac{48+2}{8}\Rightarrow 6+\frac{2}{8}=6+\frac{1}{4}\)

6 hours +1/4 hours = 6 hours 15 min

Therefore, the time taken by Jesse is 6 hours 15 min.
