Question

Courtney Drive for 30 minutes at 50 mph and for one hour at 40 mph how far has he traveled all together

Answer 1

Explanation:40 mph = 64.3738 kph

kph/3.6 = m/s

64.3738/3.6 = 17.8816 m/s

30 mins in seconds = 30 x 60 = 1800 s

1800 s x 17.8816 m/s = 32186.88 m or 32.18688 km or 20 miles
