As it is now, given that, in the 1 of calories, there are 4.18 joules, and that we wonder how many joules it has given 148 calories. So we multiply 148 cal is 4.18 joules. 148 cal x 4.18 J, and this will give us 618.64 Joules. Around this off and the result would be 619 Joules. Therefore, the correct answer would be option D. J. 619
