The earth rotates 360o of longitude every 24 hours, so it takes 24 ÷ 360 hours to rotate 1o of longitude: 24 ÷ 360 hours = 24/360 hours = 1/15 hours = 1/15 x 60 minutes = 4 minutes The sun will cross 1o of longitude in the same time that the earth takes to rotate 1o of longitude, namely 4 minutes.

Speed = Distance/Time Speed = 1 mile/5 minutes x (60 minutes/1 hour) Speed = 60 miles.minutes/5 minutes.hour (cross minutes) Speed = 60 miles/5 hours Speed = 12 miles an hour

* To find the mean (or average) of a standard frequency table, you must firstly cross-multiply the frequncies with the independent variable in the left column. * Then, add up these products and divide by the total number of frequencies. * For grouped frequency tables, you must find a mid-point, a half-way value in each group, before cross-multiplying.

No you only cross multiply when your working with percent
