1 ton=2000lb
total weight=2000
we want total weight=weight of cans
weight of cans=weight of 1 can times number of cans
W of cans=1/25c
total weight=weight of cans
2000=1/25c
times 25/1 both sides
50000=c
50,000 cans
Answer:
Zac will finish, Pam won’t
Step-by-step explanation:
Let’s have the individual reading speeds
The individual reading speeds are the number of pages divided by hours taken
For Pam; 126/3 = 42 pages per hour
For Zac; 180/4 = 45 pages per hour
In five hours, Zac would read; 45 * 5 = 225 pages
In five hours, Pam would read 42 * 5 = 210 pages
