The work needs some unit conversions. The time given is already in mixed units, so this takes a bit of work on its own. Do that conversion FIRST just for comfort. Use unit conversions in the form of fractions, and KEEP each unit with its value.
How many hours is 2 minutes 35 seconds?
, unit of HOUR
, because need common denominator
, HOUR
Reduced to HOUR.
You want now to know how to change 1 mile into how many kilometers. The conversions you can use are these:
1 mile =5280 feet
1 foot = 12 inches
2.54 centimeters = 1 inch
100 centimeters = 1 meter
1 kilometer = 1000 meters
You should be able to do the rest and to finish.
