Question
Joe competes in a biathlon. He runs 5 mi in 32 min 8 sec. He rides his bike $25 \mathrm{mi}$ in 1 hr 2 min 40 sec. Find the total time for his race.
Step 1
In this case, we will convert everything to seconds for simplicity. Joe runs 5 miles in 32 minutes and 8 seconds. We know that 1 minute is equal to 60 seconds. So, we can convert 32 minutes to seconds by multiplying 32 by 60, which gives us 1920 seconds. Adding Show more…

In a team triathlon, Torie swims $\frac{1}{2}$ mi in 15 min 30 sec. David rides his bicycle 20 mi in 50 min 20 sec. Emilie runs 4 mi in 28 min 10 sec. Find the total time for the team.
Jean runs $6 \mathrm{mi}$ and then rides $24 \mathrm{mi}$ on her bicycle in a biathlon. She rides $8 \mathrm{mph}$ faster than she runs. If the total time for her to complete the race is $2.25 \mathrm{hr}$, determine her average speed running and her average speed riding her bicycle.
