1. the pizza bot travels an average of 4 miles per hour. if he gets sent on a delivery to a house 1.5 miles away. how long will it take for the bot to make the delivery and return to the restraint.
write in scientific notation
a. 401,570,000 miles
b. 403,440,000 miles
c. 782,690,000 miles
d. 1,669,490,000 miles
e. 1,202,100,000 miles

For the first question, since they travel 4 miles per hour, we want to figure out a common factor of 4 and 1.5 - 0.5 works. Since 4/0.5 is 8, we can divide 1 hour =60 minutes by 8 to get 60/8 minutes for 0.5 miles, and since 1.5/05=3, we can multiply 60/8 by 3 to get how many minutes it would take to get 1.5 miles, which is 180/8=22.5 minutes

For A, we have to write it in <number>.<numbers>*10^<number>. Since 4 is the first number, we write it as 4.01570000*10^<number>. Since there are 8 numbers after 4, we have 4.01570000*10^8. I challenge you to use this for the rest of your problems!
