A car's speed is 45 miles per hour. How far will it go in 4 hours and 20 minutes?
2 answers:
195 miles
45x4=180
45 divided by 3=15
180+15=195
45 x 4 = 180
60 (minutes in 1 hour) divided by 45 =.75 miles per minute
.75 multiplied by 20 = 15
Total 180 + 15 = 195 miles
Or 4hrs x 60min = 240min
240+20= 260 (convert all into minutes)
260 multiplied by .75=195
