Answer:
d= 4t
Step-by-step explanation:
to find distance, the equation is speed multiplied by time and in this question we are given the time and distance so we have to divide 9km by 2.25hrs to find the speed: 9÷2.25= 4 so, the equation would be d=4t which means that to find distance we need to multiply 4 by the time.
Answer:
60m
Step-by-step explanation:
height =2+2×(let x be the length of the base)
area=1/2bh
30=1/2(2+2×)
30=2/2+2×/2
30=1+2×/2
30=1+×
30-1=×
29=
height=2+2×
2+2(29)
2+58
60
therefore the height is 60m
