Answer:
m – 12 = 20
Step-by-step explanation:
We see "equals 20", so we can automatically write:
= 20
Whenever something says "than", that means the two things they're saying need to be flipped. For example, 5 less than 1 would be 1 - 5.
So "12 less than a number <em>m</em>" would be m – 12.
Putting it all together would be:
m – 12 = 20
You would need to know the rate at which Jeremy climbs to determine your answer.
Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles
