To find their average miles per hour we can divide the total miles by the hour used:
4 2/3 ÷ 1 2/3
=4x3+2/3 ÷ 1x3+2/3
=14/3 ÷ 5/3
In division, when we switch the place of numerator and denominator, we can change it to multiplication which makes the calculation easier as we can factorize the numbers.
=14/3 x 3/5
Factorize 3 in both amounts:
=14/1 x 5/1
=14/5
=2.8 miles/hour
Therefore their average speed is 2.8 miles/hour.
Hope it helps!
31) 27
32) 75
33) 74
34) 90 (because it’s a right angle and adds up to 180)
Answer:
Step-by-step explanation:
what grade are you on lemme help you
For
|a|>b
assume
a>b and a<-b
|t+4|>10
assume
t+4>10 and t+4<-10
solve each
minus 4 both sides
t>6 and t<-14
A is answer
